Abstract: On open pit mines of Kuzbass there is a fairly clear separation of the whole developed coal-and-rock strata into a coalless and coal-bearing zone. When conducting excavating and loading operations in these zones, there is also a difference between the technologies used and primarily excavation equipment, the main types of which are electric and hydraulic shovels. Backhoes have been used for quite a while on the open pits of Kuzbass, while remaining a relatively new type of excavating equipment. In particular, up to now there has not been developed an album of standard (typical) technological schemes for mining operations by backhoes (for hydraulic shovels, this document is also absent). In this way, we can draw a preliminary conclusion that technological schemes for this type of equipment are developed mainly in the engineering departments of mining enterprises. This article provides information on the handling of loading and unloading operations on various open pits of Kuzbass, gives a brief description of the equipment used and presents technological schemes for working out the coal-bearing zones.
